Demonstration circuit 1939 is a 36V, 5A, 2-quadrant CVCC step-down μModule® regulator featuring the LTM®8052A. The demo circuit is designed for a 2.5V output from an input voltage range of 6V to 36V. The output can source 5A or sink 5A. The circuit can be operated in either constant voltage mode or constant current mode.

The ADP2108 evaluation board is a complete 600 mA, step-down regulator solution that tests the ADP2108, a high efficiency, low quiescent current step-down, dc-to-dc converter available in WLCSP and TSOT packages. The evaluation board is available in standard voltage options.

The MIC26603 DC-DC regulator operates over an input supply range of 4.5V to 28V and provides a regulated output at up to 6A of output current. The output voltage is adjustable to 0.8V with a typical accuracy of ±1%, and the device operates at a switching frequency of 600 kHz.

PMP9379 reference design is a positive and negative 15V output supply capable of delivering 0.5A per rail using the LM46002. The input voltage range is 18V to 42V in. PMP9379 uses external circuitry to ensure that the +/-15V output track each other, i.e. the output voltage above and below 0V are well controlled and accurately balanced.

The LMR10510/LMR10515/LMR10520 is a PWM DC/DC buck (step-down) regulator. With a switching frequency of 3MHz or 1.6MHz the overall solution size is very compact and requires a minimum number of components. The LMR10510/LMR10515/LMR10520 Demo Board is designed to provide the design engineer with a fully functional power converter to evaluate the LMR10510/LMR10515/LMR10520 series of buck regulators…

The TLV62130 is a 3 A, synchronous, step-down converter in a 3x3-mm, 16-pin QFN package. TLV62130EVM-505 (HPA505-004) uses the TLV62130 and is set to a 3.3 V output. The EVM operates with full-rated performance with an input voltage between 4 V and 17 V.

The TPS62175 is a 500 mA, synchronous, step-down converter in a 2x3 mm, 10-pin WSON package. Both fixed and adjustable output voltage units are available. The TPS62175EVM-098 (PWR098-001) uses the TPS62175 adjustable version and is set to a 3.3 V output. The EVM operates with full-rated performance with an input voltage between 4.75 V and 28 V.

This application note details the main features and application advantages of this new synchronous step-down regulator.

This demonstration board is based on the ST8R00W family of synchronous step-up DC-DC converters with current output cut-off function that provide up to 1 A over an input voltage range of 4 V to 6 V and an output voltage range of 6 V to 12 V.
